A combination of a printing head supporting carriage in a printer, and an ink ribbon cassette adapted for mounting on the carriage at an angle thereto and having a recess in which a printing head can be positioned. The cassette has at least one positioning pin at its bottom. A resilient lever is provided on the peripheral surface of the cassette which is substantially perpendicular to the bottom thereof. The lever has a lower end secured to the peripheral surface and a free upper end. The carriage has at its top a first inclined surface adapted to support the bottom of the cassette thereon, and having a hole for receiving the pin of the cassette therein. The carriage also has at its top a second inclined surface which is substantially perpendicular to the first inclined surface, and adapted to support the peripheral surface of the cassette thereon. The lever is engageable with the second inclined surface to hold the cassette on the carriage. The lever is elastically movable for disengagement from the second inclined surface. A resilient member is provided on the carriage for retaining the pin of the cassette in the hole.
